Let's divide 203798 by 7
The aim is to understand the frequency of 7 in 203798.

Step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 7

Let's proceed to step 2:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 14 from 20 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 7

Moving on to step 3:
If we divide 63 by 7, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 29.0
The remainder is 0 after subtracting 63 from 63.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 7

Let's proceed to step 4:
7 goes into 7 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 291.0
Deduct 7 from 7 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 7

Step 5:
9 divided by 7 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 2911.0
Deduct 7 from 9 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 7

Step 6:
The number 7 fits into 28 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 29114.0
If we take 28 away from 28, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
If we divide 0 by 7, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29114.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29114.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 29114.0 and a remainder of 0.0.
